Dick Whiteside's "Pyramid Quad" Antenna

Dick whiteside, W6OHK, designed this unique 40, 20, 15 & 10
meter "Pyramid Quad" in 1950. He constructed it in 1975. It went
down in a windstorm in 1983.

The driven element of this unique antenna was like a double-Z quad
(like a swastika). It functioned on 40-meters as two 40-meter dipoles
folded over and 90-degrees out of phase. The antenna contained two half-wave
antennas on 15-meters that were 90-degrees out-of-phase and spaced a half-wave
apart.
